Application filed February 27, 1922. Serial no. 539,629.

T 0 all whom it may concern:

Be it known that we, THOMAS H. JAMIE? son and LOUIS Gr. Marin, citizens of the United States, and residents of Wichita, in the county of Sedgwick and State of Kansas, have inventeda certain new and useful Fuel Vaporizer for Internal-Combustion Motors, of which the following is a specification.

Our invention relates to means for warming the fuel vapor asit passes from the carbureter to the intake manifold of any internal combustion motor. I

As is well known, with the low-test gasoline in general use as fuel, the starting of a cold motoroften requires several operations of the crank or starter, with its loss of time,

its drain on the battery, and its pumping of liquid gasoline into the motor cylinders. In

cold weather it is often impossible to start a gas engine until it has been primed or its intake manifold heated in some manner.

The object of our invention is to provide a simple, inexpensive electrical device, easily attachable to any gas motor, and adapted for warming the fuel vapor as it enters the manifold, so that the first sparks will result in ignition.

In the accompanying drawings, Fig. 1 represents the device in side elevation in position as a gasket between a carbureter and and an intake manifold, the latter being in vertical section; Fig. 2 is an enlarged vertical section of the device when detached; Figs. 3 and 4 are similar sectional views, showin modified forms of heating coils; Fig. 5 Is an elevation of the form shown by Fig. 3; and Fig. 6 is a sectional view of a split base-plate for a device of this kind.

The device consists essentially of a flat; plate 1, of insulating material, and a coil of resistance wire 2, mounted in an opening in the plate, with terminalsfl connected-to a pair of binding-posts 5. The plate 1 is cut or moulded in a shape and size to register with the union flanges of the carbureter and intake manifold of any make of motor, and the screw-holes 6 are located accordingly. The plate 1, shown in Fig. 1, has the same contour as the flange 7 of the carbureter 8 and the flange 9 of the manifold 10, excepting that the portion 1 of said plate, bearing the posts 5, projects above said flanges.

In the type of cylinder-block shown, the

manifold 10 is cast integral with the block;

. ofthe fuel-port 3.

but thepreheating of fuel thus afforded occurs only'when the motor is hot.

The opening 3 is formed to register insize and shape with the fuel-passage in which it is to be placed. i I

In this device the terminals 4 of the coil 2 are sunk, orimbedded in, the plate 1. One way in which this may be effected is shown diagrammatically by Fig. 6. The plate (1) is split along its longitudinal axis downwardly from the end portion 1' to or below the top The terminal binding posts 5 extend transversely through'the proecting portion 1 and when fully assembled connect to the heating element terminals wlthin' the plate 1 and bind the split portions together. v

The length and gage of the wire forming the coil, are so proportioned that when the coil is energized by cu rrent from the battery of the vehicle for which the device is intended (or from a stationary battery in the case of a stationary motor) the coil will become heated to a degree suflicient for its purpose, but not to a red heat. V This coil may be made a simple helix (as 12, Fig. 3). We prefer that the coil be made to lie entirely within the manifold; but it. may be formed as shown at 13, Fig. has

PA-TENT F E adapted to lie partly in the manifold and partly in the outlet-port of a carbureter.

For economizing the battery current, a small step-down converter might be interposed between the device and the battery leads. This, however, is not a necessity.

A switch (not shown) mounted on theinstrument-board, will be connected in series with one or both of the circuit-wires 14 and will be normally'open. Whenever the cold motor is to be started, unless the atmospheric temperature is high, the operator closes'said switch; electricity, then flows through the wires 14, 2 and 3; the wire 2 becomes warm,

or hot, and the vapor issuing from the carbureter past and through ,thecoil becomes warmed or heated, so that it arrives at the switch 7 has the desirable features above set forth. We Wish it understood that the details of construction may be varied, Within the scope of the appended claims, without departing from the essential feature of the invention.

e new claim, and desire to secure by Letters Patent:

1. A gasket plate for a fuel vaporizer comprising a sheet of insulating material having a port opening therein, the said plate being split along the axial plane of the sheet from one end thereof inwardly to meet said port opening.

2. A gasket plate for a fuel vaporizer comprisinga sheet of insulating material having a portopening therein, the said plate being split along" theaXial plane of the sheet from one end thereof inwardly to meet said port opening and adapted to be spread apart to receive renewal elements of high electric resistance; and binding posts for said elements transversely extending through said split portions and for clamping said split portions together.

In testimony whereof, we aflix our signatures.
